Compressor rotor blade airfoils

ABSTRACT

A rotor blade includes an airfoil having an airfoil shape. The airfoil shape has a nominal profile substantially in accordance with Cartesian coordinate values of X, Y and Z set forth in one of Table I, Table II, Table III, Table IV, Table V, Table VI, Table VII, Table VIII, Table IX, Table X, Table XI, or Table XII. The Cartesian coordinate values of X, Y and Z are non-dimensional values from 0% to 100% convertible to dimensional distances expressed in a unit of distance by multiplying the Cartesian coordinate values of X, Y and Z by a scaling factor of the airfoil in the unit of distance. The X and Y values, when connected by smooth continuing arcs, define airfoil profile sections at each Z value. The airfoil profile sections at Z values are joined smoothly with one another to form a complete airfoil shape.

FIELD

The present disclosure relates to an airfoil for a compressor rotorblade disposed within a stage of a compressor section of a land-basedgas turbine system and, more particularly, relates to a shape defining aprofile for an airfoil of a compressor rotor blade.

BACKGROUND

Some simple cycle or combined cycle power plant systems employturbomachines in their design and operation. Generally, turbomachinesemploy airfoils (e.g., stator vanes or nozzles and rotor blades), whichduring operation are exposed to fluid flows. These airfoils areconfigured to aerodynamically interact with the fluid flows and totransfer energy to or from these fluid flows as part of powergeneration. For example, the airfoils may be used to compress fluid,create thrust, to convert kinetic energy to mechanical energy, and/or toconvert thermal energy to mechanical energy. As a result of thisinteraction and conversion, the aerodynamic characteristics of theseairfoils may result in losses that have an impact on system and turbineoperation, performance, thrust, efficiency, and power.

BRIEF DESCRIPTION

Aspects and advantages of the rotor blades and turbomachines inaccordance with the present disclosure will be set forth in part in thefollowing description, or may be obvious from the description, or may belearned through practice of the technology.

In accordance with one embodiment, a rotor blade is provided. A rotorblade includes an airfoil having an airfoil shape. The airfoil shapehaving a nominal profile substantially in accordance with Cartesiancoordinate values of X, Y and Z set forth in one of Table I, Table II,Table III, Table IV, Table V, Table VI, Table VII, Table VIII, Table IX,Table X, Table XI, or Table XII. The Cartesian coordinate values of X, Yand Z are non-dimensional values from 0% to 100% convertible todimensional distances expressed in a unit of distance by multiplying theCartesian coordinate values of X, Y and Z by a scaling factor of theairfoil in the unit of distance. The X and Y values, when connected bysmooth continuing arcs, define airfoil profile sections at each Z value.The airfoil profile sections at Z values being joined smoothly with oneanother to form a complete airfoil shape.

The airfoil shape (e.g., the airfoil shape 150 in FIGS. 3 and 4) has anominal profile substantially in accordance with Cartesian coordinatevalues of X, Y and Z set forth in one of Table I, Table II, Table III,Table IV, Table V, Table VI, Table VII, Table VIII, Table IX, Table X,Table XI, or Table XII. Tables I-XII defines a plurality of airfoilprofile sections of the airfoil (e.g., the airfoil 100 in FIGS. 3 and 4)at respective Z-positions. For each airfoil profile section oftheairfoil at each Z position, the points defined by the X and Ycoordinates are connected together by smooth continuing arcs thereby todefine the shape of that airfoil profile section. Also, adjacent airfoilprofile sections along the Z-direction are connected together by smoothcontinuing surfaces. Thus, the complete airfoil shape is defined.Advantageously, this airfoil shape tends to provide for improvedaerodynamic efficiency of the airfoil when compared to conventionalairfoil designs.

In accordance with another embodiment, a rotor blade is provided.

The Cartesian coordinate values of X, Y and Zare non-dimensional values from 0% to 100% convertible to dimensionaldistances expressed in a unit of distance by multiplying the Cartesiancoordinate values of X, Y and Z by a scaling factor of the airfoil inthe unit of distance. The X and Y values, when connected by smoothcontinuing arcs, define suction-side profile sections at each Z value.The suction-side profile sections at the Z values being joined smoothlywith one another to form a complete airfoil suction-side shape.

In accordance with yet another embodiment, a turbomachine is provided.The turbomachine includes a compressor section, a turbine sectiondownstream from the compressor section, and a combustion sectiondownstream from the compressor section and upstream from the turbinesection. A rotor blade is disposed within one of the compressor sectionor the turbine section. The rotor blade includes an airfoil having anominal suction-side profile substantially in accordance withsuction-side Cartesian coordinate values of X, Y and Z set forth in oneof Table I, Table II, Table III, Table IV, Table V, Table VI, Table VII,Table VIII, Table IX, Table X, Table XI, or Table XII. The Cartesiancoordinate values of X, Y and Z are non-dimensional values from 0% to100% convertible to dimensional distances expressed in a unit ofdistance by multiplying the Cartesian coordinate values of X, Y and Z bya scaling factor of the airfoil in the unit of distance. The X and Yvalues, when connected by smooth continuing arcs, define suction-sideprofile sections at each Z value.

For example,“generally vertical” includes directions within ten degrees of verticalin any direction, e.g., clockwise or counter-clockwise.

Referring now to the drawings, FIG. 1 illustrates a schematic diagram ofone embodiment of a turbomachine, which in the illustrated embodiment isa gas turbine 10. Although an industrial or land-based gas turbine isshown and described herein, the present disclosure is not limited to aland based and/or industrial gas turbine unless otherwise specified inthe claims. For example, the invention as described herein may be usedin any type of turbomachine including but not limited to a steamturbine, an aircraft gas turbine, or a marine gas turbine.

As shown, gas turbine 10 generally includes an inlet section 12, acompressor section 14 disposed downstream of the inlet section 12, aplurality of combustors (not shown) within a combustor section 16disposed downstream of the compressor section 14, a turbine section 18disposed downstream of the combustor section 16, and an exhaust section20 disposed downstream of the turbine section 18. Additionally, the gasturbine 10 may include one or more shafts 22 coupled between thecompressor section 14 and the turbine section 18.

The multi-stage axial compressor section or compressor section 14 maygenerally include a plurality of rotor disks 24 (one of which is shown)and a plurality of rotor blades 44 extending radially outwardly from andconnected to each rotor disk 24. Each rotor disk 24 in turn may becoupled to or form a portion of the shaft 22 that extends through thecompressor section 14. The compressor section 14 may further include oneor more stator vanes 50 arranged circumferentially around the shaft 22.The stator vanes 27 may be fixed to a static casing or compressor casing48 that extends circumferentially around the rotor blades 44.

The turbine section 18 may generally include a plurality of rotor disks28 (one of which is shown) and a plurality of rotor blades 30 extendingradially outwardly from and being interconnected to each rotor disk 28.Each rotor disk 28 in turn may be coupled to or form a portion of theshaft 22 that extends through the turbine section 18. The turbinesection 18 further includes a turbine casing 33 that circumferentiallysurround the portion of the shalt 22 and the rotor blades 30, thereby atleast partially defining a hot gas path 32 through the turbine section18. The turbine casing 33 may be configured to support a plurality ofstages of stationary nozzles 29 extending radially inwardly from theinner circumference of the turbine casing 33.

During operation, a working fluid such as air flows through the inletsection 12 and into the compressor section 14 where the air isprogressively compressed, thus providing pressurized air to thecombustors of the combustor section 16. The pressurized air is mixedwith fuel and burned within each combustor to produce combustion gases34. The combustion gases 34 flow through the hot gas path 32 from thecombustor section 16 into the turbine section 18, wherein energy(kinetic and/or thermal) is transferred from the combustion gases 34 tothe rotor blades 30, causing the shaft 22 to rotate. The mechanicalrotational energy may then be used to power the compressor section 14and/or to generate electricity. The combustion gases 34 exiting theturbine section 18 may then be exhausted from the gas turbine 10 via theexhaust section 20.

FIG. 2 illustrates a cross-sectional side view of an embodiment of thecompressor section 14 of the gas turbine 10 of FIG. 1, which is shown asa multi-stage axial compressor section 14, in accordance withembodiments of the present disclosure. As shown in FIGS. 1 and 2, thegas turbine 10 may define a cylindrical coordinate system. Thecylindrical coordinate system may define an axial direction A (e.g.downstream direction) substantially parallel to and/or along an axialcenterline 23 of the gas turbine 10, a radial direction R perpendicularto the axial centerline or rotary axis 23, and a circumferentialdirection C extending around the axial centerline 23.

In operation, air 15 may enter the compressor section 14 in the axialdirection A through the inlet section 12 and may be pressurized in themulti-stage axial compressor section 14. The compressed air may then bemixed with fuel for combustion within the combustor section 16 to drivethe turbine section 18, which rotates the shaft 22 in thecircumferential direction C and, thus, the multi-stage axial compressorsection 14. The rotation of the shaft 22 also causes one or more rotorblades 44 (e.g., compressor rotor blades) within the multi-stage axialcompressor section 14 to draw in and pressurize the air received by theinlet section 12.

The multi-stage axial compressor section 14 may include a rotor assembly46 having a plurality of rotor disks 24. Rotor blades 44 may extendradially outward from the rotor disks 24. The entire rotor assembly 46(e.g. rotor disks 24 and rotor blades 44) may rotate in thecircumferential direction C during operation of the gas turbine 10. Therotor assembly 46 may be surrounded by a compressor casing 48. Thecompressor casing may be static or stationary, such that the rotorassembly 46 rotates relative to the compressor casing 48. Stator vanes50 (e.g., variable stator vanes and/or fixed stator vanes) may extendradially inward from the compressor casing 48. As shown in FIG. 2, oneor more stages of the stator vanes 50 may be variable stator vanes 51,such that an angle of the stator vane 50 may be selectively actuated(e.g. by a controller 200). For example, in the embodiments shown inFIG. 2, first two stages of the compressor section 14 may includevariable stator vanes 51. In many embodiments, as shown, the rotorblades 44 and stator vanes 50 may be arranged in an alternating fashion,such that most of the rotor blades 44 are disposed between two statorvanes 50 in the axial direction A.

In some embodiments, the compressor casing 48 of the compressor section14 or the inlet section 12 may have one or more sets of inlet guidevanes 52 (IGVs)(e.g., variable IGV stator vanes). The inlet guide vanes52 may be mounted to the compressor casing 48, spaced apart from oneanother in the circumferential direction C, and may be operable tocontrol the amount of air 15 that enters the compressor section 14.Additionally, an outlet 56 of the compressor section 14 may have a setof outlet guide vanes 58 (OGVs). The OGVs 58 may be mounted to thecompressor casing 48, spaced apart from one another in thecircumferential direction C, and may be operable to control the amountof air 15 that exits the compressor section 14.

In exemplary embodiments, as shown in FIG. 2, the variable stator vane51, the IGVs 52, and the OGVs may each be configured to vary its vaneangle relative to the gas flow (e.g. air flow) by rotating the vane 51,52, 58 about an axis of rotation (e.g., radially oriented vane shaft).However, each variable stator vane 51 (including the IGVs 52 and theOGVs 58) may be otherwise stationary relative to the rotor blades 44. Incertain embodiments, the variable stator vanes 51, the IGVs 52, and theOGVs 58 may be coupled to an actuator 19 (e.g., electric drive,pneumatic drive, or hydraulic drive). The actuators 19 may be inoperable communication (e.g. electrical communication) with a controller200. The controller may be operable to selectively vary the vane angle.In other embodiments, all of the stator vanes 50 may be fixed, such thatthe stator vanes 50 are configured to remain in a fixed angular position(e.g. the vane angle does not vary).

The compressor section 14 may include a plurality of rows or stagesarranged in a serial flow order, such as between 2 to 30, 2 to 25, 2 to20, 2 to 14, or 2 to 10 rows or stages, or any specific number or rangetherebetween. Each stage may include a plurality of rotor blades 44circumferentially spaced about the axial centerline 23 and a pluralityof stator vanes 50 circumferentially spaced about the axial centerline23. In each stage, the multi-stage axial compressor section 14 mayinclude 2 to 1000, 5 to 500, or 10 to 100 of circumferentially arrangedrotor blades 44, and 2 to 1000, 5 to 500, or 10 to 100 ofcircumferentially arranged stator vanes 50. In particular, theillustrated embodiment of the multi-stage axial compressor section 14includes 22 stages (e.g. S1-S22).

It may be appreciated that each stage has a set of rotor blades 44disposed at a first axial position and a set of stator vanes 50 disposedat a second axial position along the length of the compressor section14. In other words, each stage has the rotor blades 44 and stator vanes50 axially offset from one another, such that the compressor section 14has an alternating arrangement of rotor blades 44 and stator vanes 50one set after another along the length of the compressor section 14.Each set of rotor blades 44 extends (e.g., in a spaced arrangement) inthe circumferential direction C about the shaft 22, and each set ofstator vanes 50 extends (e.g., in a spaced arrangement) in thecircumferential direction C within the compressor casing 48.

While the compressor section 14 may include greater or fewer stages thanis illustrated, FIG. 2 illustrates an embodiment of the compressorsection 14 having twenty two stages arranged in a serial flow order andidentified as follows: first stage S1, second stage S2, third stage S3,fourth stage S4, fifth stage S5, sixth stage S6, seventh stage S7,eighth stage S8, ninth stage S9, tenth stage S10, eleventh stage S11,twelfth stage S12, thirteenth stage S13, and fourteenth stage S14,fifteenth stage S15, sixteenth stage S16, seventeenth stage S17,eighteenth stage S18, nineteenth stage S19, twentieth stage S20,twenty-first stage S21, and twenty-second stage S22. In certainembodiments, each stage may include rotor blades 44 and stator vanes 50(e.g., fixed stator vanes 50 and/or variable stator vanes 51). As usedherein, a rotor blade 44 disposed within one of the sections S1-S22 ofthe compressor section 14 may be referred to by whichever stage it isdisposed within, e.g. “a first stage compressor rotor blade,” “a secondstage compressor rotor blade,” “a third stage compressor rotor blade,”etc.

In use, the rotor blades 44 may rotate circumferentially about thecompressor casing 48 and the stator vanes 50. Rotation of the rotorblades 44 may result in air entering the inlet section 12. The air isthen subsequently compressed as it traverses the various stages (e.g.,first stage S1 to twenty-second stage S22) of the compressor section 14and moves in the axial direction 38 downstream of the multi-stage axialcompressor section 14. The compressed air may then exit through theoutlet 56 of the multi-stage axial compressor section 14. As discussedabove, the outlet 56 may have a set of outlet guide vanes 58 (OGVs). Thecompressed air that exits the compressor section 14 may be mixed withfuel, directed to the combustor section 16, directed to the turbinesection 18, or elsewhere in the gas turbine 10.

TABLES I through XII below each contain coordinate data that describes arespective airfoil shape (or surface profile). In exemplary embodiments,the airfoil shapes defined by each of TABLES I through XII describe arotor blade 44 and/or the stator vane 50 of the compressor section 14.In certain embodiments, the airfoil shapes defined by each of TABLES Ithrough XII describe an IGV 52 and/or an OGV 58 of the compressorsection 14.

The IGV 52, the stages (e.g. S1-S22) of rotor blades 44 and stator vanes50, and the OGV 58 of the compressor section 14 may be grouped into oneor more sections or portions of the compressor section 14 for referencepurposes. For the purposes of the grouping, portions the compressorsection 14 may be expressed in terms of a percentage, such as apercentage of the compressor section 14 from the inlet (e.g. 0% of thecompressor section 14) to the outlet (e.g. 100% of the compressorsection 14) in the axial or downstream direction. In this way, thecompressor section 14 may include, in a serial flow order, an earlystage 60, a mid stage 62, and a late stage 64. In particular, the earlystage 60 may include from approximately 0% to approximately 25% of thecompressor section 14 (e.g. from the IGV 52 to about the fifth stage S5or the sixth stage S6). The mid stage 62 may include from approximately25% to approximately 75% of the compressor section 14 (e.g. from aboutthe fifth stage S5 or the sixth stage S6 to about the sixteenth stageS16 or the seventeenth stage S17). The late stage 64 may include fromapproximately 75% to approximately 100% of the compressor section 14(e.g. from about the sixteenth stage S16 or the seventeenth stage S17 tothe OGV 58).

Accordingly, the Cartesian coordinate data contained within each ofTABLES I through V may correspond to an airfoil shape of an airfoil 100disposed within the early stage 60 of the compressor section 14. TheCartesian coordinate data contained within each of TABLES VI through XImay correspond to an airfoil shape of an airfoil 100 disposed within themid stage 62 of the compressor section 14. The Cartesian coordinate datacontained within TABLE XII may correspond to an airfoil shape of anairfoil 100 disposed within the late stage 64 of the compressor section14.

For example, in exemplary embodiments, the Cartesian coordinate datacontained within TABLE I may correspond to an airfoil shape of anairfoil 100 disposed on a rotor blade 44 within the second stage S2 ofthe compressor section 14. The Cartesian coordinate data containedwithin TABLE II may correspond to an airfoil shape of an airfoil 100disposed on a rotor blade 44 within the third stage S3 of the compressorsection 14. The Cartesian coordinate data contained within TABLE III maycorrespond to an airfoil shape of an airfoil 100 disposed on a rotorblade 44 within the fourth stage S4 of the compressor section 14. TheCartesian coordinate data contained within TABLE IV may correspond to anairfoil shape of an airfoil 100 disposed on a rotor blade 44 within thefifth stage S5 of the compressor section 14. The Cartesian coordinatedata contained within TABLE V may correspond to an airfoil shape of anairfoil 100 disposed on a rotor blade 44 within the sixth stage S6 ofthe compressor section 14. The Cartesian coordinate data containedwithin TABLE VI may correspond to an airfoil shape of an airfoil 100disposed on a rotor blade 44 within the seventh stage S7 of thecompressor section 14. The Cartesian coordinate data contained withinTABLE VII may correspond to an airfoil shape of an airfoil 100 disposedon a rotor blade 44 within the eleventh stage S11 of the compressorsection 14. The Cartesian coordinate data contained within TABLE VIIImay correspond to an airfoil shape of an airfoil 100 disposed on a rotorblade 44 within the twelfth stage S12 of the compressor section 14. TheCartesian coordinate data contained within TABLE IX may correspond to anairfoil shape of an airfoil 100 disposed on a rotor blade 44 within thefourteenth stage S14 of the compressor section 14. The Cartesiancoordinate data contained within TABLE X may correspond to an airfoilshape of an airfoil 100 disposed on a rotor blade 44 within thefifteenth stage S15 of the compressor section 14. The Cartesiancoordinate data contained within TABLE XI may correspond to an airfoilshape of an airfoil 100 disposed on a rotor blade 44 within theseventeenth stage S17 of the compressor section 14. The Cartesiancoordinate data contained within TABLE XII may correspond to an airfoilshape of an airfoil 100 disposed on a rotor blade 44 within theeighteenth stage S18 of the compressor section 14.

However, in various other embodiments, each of TABLES I through XII maycontain Cartesian coordinate data of an airfoil shape of an airfoil 100that may be disposed on a rotor blade 44 or stator blade 50 in any stageS1-S22 of the compressor section 14. Accordingly, the airfoil shapedefined by each of TABLES I through XII should not be limited to anyparticular stage of the compressor section 14 unless specificallyrecited in the claims.

FIG. 3 illustrates a perspective view of a rotor blade 44, which may beincorporated in any stage (e.g. S1 through S22) of the compressorsection 14, in accordance with embodiments of the present disclosure.

As shown, the rotor blade 44 includes an airfoil 100 defining an airfoilshape 150. The airfoil 100 includes a pressure-side surface or profile102 and an opposing suction-side surface or profile 104. Thepressure-side surface 102 and the suction-side surface 104 meet orintersect at a leading edge 106 and a trailing edge 108 of the airfoil100. A chord line 110 extends between the leading edge 106 and thetrailing edge 108 (defining a chord length) such that pressure andsuction-side surfaces 102, 104 can be said to extend in chord orchordwise between the leading edge 106 and the trailing edge 108. Theleading and trailing edges, 106 and 108 respectively, may be describedas the dividing or intersecting lines between the suction-side surface104 and the pressure-side surface 102. In other words, the suction-sidesurface 104 and the pressure-side surface 102 couple together with oneanother along the leading edge 106 and the trailing edge 108, therebydefining an airfoil shaped cross-section that gradually changeslengthwise along the airfoil 100.

In operation, the rotor blades 44 rotate about an axial centerline 23exerting a torque on a working fluid, such as air 15, thus increasingenergy levels of the fluid as the working fluid traverses the variousstages S1 through S22 of the multi-stage axial compressor section 14 onits way to the combustor 26. The rotor blades 44 may be adjacent (e.g.,upstream and/or downstream) to the one or more stationary stator vanes50. The stator vanes 50 slow the working fluid during rotation of therotor blades 44, converting a circumferential component of movement ofthe working fluid flow into pressure. Accordingly, continuous rotationof the rotor blade 44 creates a continuous flow of compressed workingfluid, suitable for combustion via the combustor 26.

As shown in FIG. 3, the airfoil 100 includes a root or first end 112,which intersects with and extends radially outwardly from a base orplatform 114 of the rotor blade 44. The airfoil 100 terminates radiallyat a second end or radial tip 116 of the airfoil 100. The pressure-sideand suction-side surfaces 102, 104 can be said to extend in span or in aspan-wise direction 118 between the root 112 and/or the platform 114 andthe radial tip 116 of the airfoil 100. In other words, each rotor blade44 includes an airfoil 100 having opposing pressure-side andsuction-side surfaces 102, 104 that extend in chord or chordwise 110between opposing leading and trailing edges 106, 108 and that extend inspan or span-wise 118 between the root 112 and the radial tip 116 of theairfoil 100.

In particular configurations, the airfoil 100 may include a fillet 72formed between the platform 114 and the airfoil 100 proximate to theroot 112. The fillet 72 can include a weld or braze fillet, which can beformed via conventional MIG welding, TIG welding, brazing, etc., and caninclude a profile that can reduce fluid dynamic losses as a result ofthe presence of fillet 72. In particular embodiments, the platform 114,the airfoil 100 and the fillet 72 can be formed as a single component,such as by casting and/or machining and/or additive manufacturing (suchas 3D printing) and/or any other suitable technique now known or laterdeveloped and/or discovered.

In various implementations, the rotor blade 44 includes a mountingportion 74 (such as a dovetail joint), which is formed to connect and/orto secure the rotor blade 44 to the rotor disk 24. For example, themounting portion 74 may include a T-shaped structure, a hook, one ormore lateral protrusions, one or more lateral slots, or any combinationthereof. The mounting portion 74 (e.g., dovetail joint) may beconfigured to mount into the rotor assembly 46 or the compressor casing48 in an axial direction A, a radial direction R, and/or acircumferential direction C (e.g., into an axial slot or opening, aradial slot or opening, and/or a circumferential slot or opening).

An important term in this disclosure is “profile”. The profile is therange of the variation between measured points on an airfoil surface andthe ideal position listed in any one of TABLES I through XII. The actualprofile on a manufactured turbine rotor blade will be different thanthose in TABLES I through XII, and the design is robust to thisvariation meaning that mechanical and aerodynamic function are notimpaired. As noted above, a + or −5% profile tolerance is used herein.The X, Y and Z values are all non-dimensionalized relative to theairfoil height.

The airfoil 100 of the rotor blade 44 has a nominal profile at anycross-section taken between the platform 114 or the root 112 and theradial tip 116, e.g., such as the cross section shown in FIG. 4. A“nominal profile” is the range of variation between measured points onan airfoil surface and the ideal position listed in TABLES I throughXII. The actual profile on a manufactured compressor blade may bedifferent from those in TABLES I through XII (e.g., due to manufacturingtolerances), and the design is robust to this variation, meaning thatmechanical and aerodynamic function are not impaired.

The Cartesian coordinate values of X, Y, and Z provided in each ofTABLES I through XII are dimensionless values scalable by a scalingfactor, as measured in any given unit of distance (e.g., inches). Forexample, the X, Y, and Z values in each of TABLES I through XII are setforth in non-dimensionalized units, and thus a variety of units ofdimensions may be used when the values are appropriately scaled by ascaling factor. As one example only, the Cartesian coordinate values ofX, Y and Z may be convertible to dimensional distances by multiplyingthe X, Y and Z values by a scaling factor. The scaling factor may besubstantially equal to 1, greater than 1, or less than 1. For example,the Cartesian coordinate values of X, Y, and Z may be convertible todimensional distances by multiplying the X, Y, and Z values by thescaling factor. The scaling factor, used to convert the non-dimensionalvalues to dimensional distances, may be a fraction (e.g., ½, ¼, etc.),decimal fraction (e.g., 0.5, 1.5, 10.25, etc.), integer (e.g., 1, 2, 10,100, etc.) or a mixed number (e.g., 1½, 10¼, etc.). The scaling factormay be a dimensional distance in any suitable format (e.g., inches,feet, millimeters, centimeters, etc.). In various embodiments, thescaling factor may be between about 0.01 inches and about 10 inches,such as between about 0.1 inches and about 10 inches, such as betweenabout 0.1 inches and about 5 inches, such as between about 0.1 inchesand about 3 inches, such as between about 0.1 inches and about 2 inches.

In various embodiments, the X, Y, and Z values in each of TABLES Ithrough XII may be scaled as a function of the same scaling factor(e.g., constant or number) to provide a scaled-up or a scaled-downairfoil. In some embodiments, the scaling factor may be different foreach of TABLES I through XII, such that each of the TABLES I through XIIhas a unique scaling factor. In this way, each of TABLES I through XIIdefine the relationships between the respective X, Y, and Z coordinatevalues without specifying the units of measure (e.g., dimensional units)for the various airfoil 100 embodiments. Accordingly, while differentscaling factors may be applied to the respective X, Y, and Z coordinatevalues of each of TABLES I through XII to define different embodimentsof the airfoil 100, each embodiment of the airfoil 100 regardless of theparticular scaling factor is considered to be defined by the respectiveX, Y, and Z coordinate values TABLES I through XII. For example, the X,Y, and Z coordinate values of TABLES I through XII may each define anembodiment of the airfoil 100 formed with a 1:1 inch scaling factor, orformed with a 1:2 inch scaling factor, or formed with a 1:1 cm scalingfactor. It may be appreciated that any scaling factor may be used withthe X, Y, and Z coordinate values of any of TABLES I through XII,according to the design considerations of a particular embodiment.

A gas turbine hot gas path requires airfoils that meet systemrequirements of aerodynamic and mechanical blade loading and efficiency.To define the airfoil shape of each compressor rotor blade airfoil,there is a unique set or loci of points in space that meet the stagerequirements and that can be manufactured. This unique loci of pointsmeet the requirements for stage efficiency and are arrived at byiteration between aerodynamic and mechanical loadings enabling theturbine to run in an efficient, safe and smooth manner. These points areunique and specific to the system.

The loci that define the compressor rotor blade airfoil shape include aset of points with X, Y and Z dimensions relative to a reference origincoordinate system. The Cartesian coordinate system of X, Y and Z valuesgiven in each of TABLES I through XII below defines the airfoil shapes(which include the various airfoil profile sections) of an airfoilbelonging to one or more compressor rotor blades or compressor statorvanes at various locations along its height (or along the span-wisedirection 118).

Each of TABLES I through XII list data for an uncoated airfoil at coldor room temperature. The envelope/tolerance for the coordinates is about+/−5% in a direction normal to any airfoil surface location and/or about+/−5% of the chord 110 in a direction nominal to any airfoil surfacelocation. In other words, the airfoil layout, as embodied by thedisclosure, is robust to this range of variation without impairment ofmechanical and aerodynamic functions. As used herein, the term ofapproximation “substantially,” when used in the phrase “substantially inaccordance with Cartesian coordinate values of X, Y and Z set forth inTable I,” refers to the envelope/tolerance for the coordinates (e.g.,+/−5% in a direction normal to any airfoil surface location and/or about+/−5% of the chord 110 in a direction nominal to any airfoil surfacelocation).

A point data origin 76 is defined at the base 114 of the airfoil 100.For example, the point data origin 76 may be defined at the root 112 ofthe airfoil 100. For example, in some embodiments, the point data origin76 may be defined at the root 112 of the airfoil 100 at the intersectionof a stacking axis (e.g., a radially extending axis) and the compressedair flowpath (e.g., a flowpath of air along the surface of the airfoil).In the embodiments presented in TABLES I through XII below, the pointdata origin 76 is defined at a transition or intersection line 78defined between the fillet 72 and the airfoil 100. The point data origin76 corresponds to the non-dimensional Z value equal to 0.

As described above, the Cartesian coordinate system has orthogonallyrelated (e.g., mutually orthogonal) X, Y and Z axes, and the X axis liesgenerally parallel to an axial centerline 23 of the shaft 22, i.e., therotary axis, and a positive X coordinate value is axial toward aforward, i.e., inlet end of the gas turbine 10. The positive Ycoordinate value extends in the direction from the suction-side surface104 to the pressure-side surface 102 and the positive Z coordinate valueis radially outwardly from the base 114 toward the radial tip 116 (e.g.,generally parallel to the radial direction of the gas turbine). All thevalues in Table I are given at room temperature and do not include thefillet 72 or coatings (not shown).

By defining X and Y coordinate values at selected locations in a Zdirection normal to the X, Y plane, an airfoil profile section 160 ofthe airfoil 100 of the rotor blade 44 may be defined at each Z distancealong the length of the airfoil 100. By connecting the X and Y valueswith smooth continuing arcs, each airfoil profile section of the airfoil100 at each distance Z may be fixed. The complete airfoil shape 150 maybe determined by smoothly connecting the adjacent profile sections toone another.

The values of TABLES I through XII are generated and shown to threedecimal places for determining the airfoil shape 150 of the airfoil 100.As the rotor blade 44 heats up during operation of the gas turbine 10,surface stress and temperature will cause a change in the X, Y and Zvalues. Accordingly, the values for the various airfoil profile sectionsgiven in TABLES I through XII define the “nominal” airfoil profile, thatis, the profile of an uncoated airfoil at ambient, non-operating ornon-hot conditions (e.g., room temperature).

There are typical manufacturing tolerances as well as coatings whichmust be accounted for in the actual profile of the airfoil 100. Eachcross-section is joined smoothly with the other cross-sections to formthe complete airfoil shape. It will therefore be appreciated that +/−typical manufacturing tolerances, i.e., +/− values, including anycoating thicknesses, are additive to the X and Y values given in each ofTABLES I through XII below. Accordingly, a distance of +/−5% in adirection normal to any surface location along the airfoil profiledefines an airfoil profile envelope for this particular rotor blade 44airfoil design, i.e., a range of variation between measured points onthe actual airfoil surface at nominal cold or room temperature and theideal position of those points as given in each of TABLES I through XIIbelow at the same temperature. The data provided in each of TABLES Ithrough XII is scalable (i.e., by a uniform geometric scaling factor),and the geometry pertains to all aerodynamic scales, at, above and/orbelow 3000 RPM. The design of the airfoil 100 for rotor blade 44 isrobust to this range of variation without impairment of mechanical andaerodynamic functions.

The airfoil 100 may include various airfoil profile sections along thespan-wise direction 118. Each of the airfoil profile sections may be“stacked” on top of one another other along the Z direction, such thatwhen connected with smooth continuous arcs, the complete airfoil shape150 may be ascertained. For example, each airfoil profile sectioncorresponds to Cartesian coordinate values of X, Y, and Z for a commonCartesian coordinate value of Z in each of TABLES I through XII.Furthermore, adjacent airfoil profile sections correspond to theCartesian coordinate values of X, Y, and Z for adjacent Cartesiancoordinate values of Z in each of TABLES I through XII.

For example, FIG. 4 illustrates an airfoil profile section 160 of anairfoil 100 from along the line 4-4 shown in FIG. 3, which may berepresentative of an airfoil profile section of the airfoil 100 at anyspan-wise location, in accordance with embodiments of the presentdisclosure. As should be appreciated, the airfoil shape 150 of theairfoil 100 may change or vary at each span-wise location (or at each Zvalue). In this way, a distinct airfoil profile section 160 may bedefined at each position along the span-wise direction 118 (or at each Zvalue) of the airfoil 100. When the airfoil profile sections 160 at eachspan-wise location (e.g. at each Z value) of the airfoil 100 areconnected together with smooth continuous lines, the complete airfoilshape 150 of the airfoil 100 may be defined or obtained.

A Cartesian coordinate system of X, Y, and Z values given in each ofTABLES I through XII below define respective suction side surfaces orprofiles 104 and a pressure side surfaces or profiles 102 of therespective airfoils 100 at various locations along the span-wisedirection 118 of the respective airfoils 100. For example, point 120defines a first pair of suction side X and Y values at the Z value ofthe airfoil profile section 160 shown in FIG. 4 (line 4-4 shown in FIG.3), while point 122 defines a second pair of pressure side X and Yvalues at the same Z value.

By defining X and Y coordinate values at selected locations in a Zdirection normal to the X-Y plane, an airfoil profile section 160 of theairfoil 100 may be obtained at each of the selected Z value location(e.g. by connecting each X and Y coordinate value at a given Z value toadjacent X and Y coordinate values of that same Z value with smoothcontinuing arcs). At each Z value or location, the suction side profile104 may joined to the pressure-side profile or surface 102, as shown inFIG. 4, to define the airfoil profile section 160. The airfoil shape 150of the airfoil 100 may be determined by smoothly connecting the adjacent(e.g., “stacked”) airfoil profile sections 160 to one another withsmooth continuous arcs.

The values in each of TABLES I through XII below are computer-generatedand shown to three decimal places. However, certain values in TABLES Ithrough XII may be shown to less than five decimal places (e.g., 0, 1,or 2 decimal places), because the values are rounded to significantfigures, the additional decimal places would merely show trailingzeroes, or a combination thereof. Accordingly, in certain embodiments,any values having less than three decimal places may be shown withtrailing zeroes out to 1, 2, or 3 decimal places. Furthermore, in someembodiments and in view of manufacturing constraints, actual valuesuseful for forming the airfoil 100 are may be considered valid to fewerthan three decimal places for determining the airfoil shape 150 of theairfoil 100.

As will be appreciated, there are typical manufacturing tolerances whichmay be accounted for in the airfoil shape 150. Accordingly, the X, Y,and Z values given in each of TABLES I through XII are for the airfoilshape 150 of a nominal airfoil. It will therefore be appreciated thatplus or minus typical manufacturing tolerances are applicable to theseX, Y, and Z values and that an airfoil 100 having a profilesubstantially in accordance with those values includes such tolerances.

As noted previously, the airfoil 100 may also be coated for protectionagainst corrosion, erosion, wear, and oxidation after the airfoil 100 ismanufactured, according to the values in any of TABLES I through XII andwithin the tolerances explained above. For example, the coating regionmay include one or more corrosion resistant layers, erosion resistantlayers, wear resistant layers, oxidation resistant or anti-oxidationlayers, or any combination thereof. For example, in embodiments wherethe airfoil is measured in inches, an anti-corrosion coating may beprovided with an average thickness t of 0.008 inches (0.20 mm), between0.001 and 0.1 inches (between 0.025 and 2.5 mm), or between 0.0001 and0.5 inches or more (between 0.0025 and 12.7 mm or more). For example, incertain embodiments, the coating may increase X and Y values of asuction side in any of TABLES I through XI by no greater thanapproximately 3.5 mm along a first suction portion, a first pressureportion, or both. It is to be noted that additional anti-oxidationcoatings may be provided, such as overcoats. The values provided in eachof TABLES I through XII exclude a coated region or coatings of theairfoil 100. In other words, these values correspond to the bare surfaceof the airfoil 100. The coated region may include one or more coatinglayers, surface treatments, or a combination thereof, over the baresurface of the airfoil 100.

TABLES I through XII below each contain Cartesian coordinate data of anairfoil shape 150 of an airfoil 100, which may be incorporated into oneof the compressor section 14 or the turbine section 18 of the gasturbine 10. For example, in many embodiments, TABLES I through XII beloweach contain Cartesian coordinate data of an airfoil shape 150 of anairfoil 100 of a rotor blade 44, which is disposed in one of the earlystage 60, the mid stage 62, or the late stage 64 of the compressorsection 14 (such as in any one of stages S1-S22).

In exemplary embodiments, TABLE I below contains Cartesian coordinatedata of an airfoil shape 150 of an airfoil 100 of a rotor blade 44,which is disposed in the early stage 60 of the compressor section 14.Specifically, TABLE I below contains Cartesian coordinate data of anairfoil shape 150 of an airfoil 100 of a rotor blade 44, which isdisposed in the second stage S2 of the compressor section 14

It will also be appreciated that the airfoil 100 disclosed in any one ofthe above TABLES I through XII may be scaled up or down geometricallyfor use in other similar gas turbine designs. Consequently, thecoordinate values set forth in any one of TABLES I through XII may bescaled upwardly or downwardly such that the airfoil profile shaperemains unchanged. A scaled version of the coordinates in any one ofTABLES I through XII would be represented by X, Y and Z coordinatevalues, with the X, Y and Z non-dimensional coordinate values convertedto units of distance (e.g., inches), multiplied or divided by a constantnumber (e.g. a scaling factor).

As shown in FIG. 4, each airfoil 100 may define a stagger angle α(alpha) measured between the chord line 110 and the axial direction A ofthe gas turbine 10. Specifically, the stagger angle α may be measuredbetween the chord line 110 of an airfoil 100 and the axial centerline 23(or rotary axis) of the gas turbine 10 at the trailing edge 108 of theairfoil 100. The stagger angle α of each airfoil 100 disclosed hereinmay advantageously vary along the span-wise direction 118 (or radialdirection R) according to a respective stagger angle distribution. Thestagger angle distribution may be a collection of stagger angles α for agiven airfoil 100 at each span-wise location (or radial location) alongthe airfoil 100.

In many embodiments, each stage S1-S22 of rotor blades 44 may include aunique stagger angle distribution, such that the collective utilizationof the stages S1-S22 of rotor blades 44 will yield a highly efficientcompressor section 14. For example, each of the airfoils 100 of therotor blades 44 within the first stage S1 may have a first stagger angledistribution, each of the airfoils 100 of the rotor blades 44 within thesecond stage S2 may have a second stagger angle distribution, and so onfor each stage (S1-S22) of the compressor section 14.

Similarly, each stage S1-S22 of stator vanes 50 may include a uniquestagger angle distribution, such that the collective utilization of thestages S1-S22 of stator vanes 50 will yield a highly efficientcompressor section 14. For example, each of the airfoils 100 of thestator vanes 50 within the first stage S1 may have a first stagger angledistribution, each of the airfoils 100 of the stator vanes 50 within thesecond stage S2 may have a second stagger angle distribution, and so onfor each stage (S1-S22) of the compressor section 14.

In accordance with embodiments of the present disclosure, FIGS. 5through 13 each illustrate a graph of a stagger angle distribution,which may belong to one or more airfoils 100 within a specified stage(e.g., S1-S22) of the compressor section 14. Each of the graphs may bein non-dimensional units. Specifically, the y-axis may be a percentagealong the span-wise direction 118 (e.g., with 0% span representing theinner diameter and 100% span representing the outer diameter). Forexample, with a rotor blade 44, 0% span may represent the base of theairfoil 100, and 100% span may represent the tip of the airfoil 100. Asfor a stator vane 50, 0% span may represent the tip of the airfoil 100,and 100% span may represent the base of the airfoil 100. The x-axis maybe a ratio between the stagger angle at a specified span-wise locationand the mid-span stagger angle (e.g., at about 50% span).

Each of the stagger angle distributions is plotted between 15% span and85% span of the respective airfoil 100 to which it belongs (e.g., 0%-15%span and 85%-100% span points are omitted). Each stagger angledistribution, when implemented in an airfoil 100 on a rotor blade 44and/or a stator vane 50 within the compressor section 14, advantageouslyincrease the aerodynamic efficiency of the airfoil 100 (as well as theentire compressor section 14) when compared to prior designs.
